Problems solved by technology

Some transparent display devices are prone to diffraction effects, resulting in ghosting when viewing a transparent display device, which affects the transparency effect, and as the pixel density (PPI) increases, the smaller the size of each transparent area, the corresponding The more serious the diffraction ghosting phenomenon is, it will affect the quality of transparent display

Abstract

A display substrate and a display device relate to but are not limited to the technical field of display, the display substrate comprises a transparent display area and a non-display area arranged on the periphery of the transparent display area, the transparent display area comprises a substrate and a plurality of display units arranged on the substrate in an array, each display unit comprises a display area and a first transparent area, the display area comprises a plurality of sub-pixels, each sub-pixel comprises a pixel driving circuit and a light-emitting element, and the pixel driving circuit is configured to drive the light-emitting element to emit light; the display area is at least partially surrounded by the first transparent area; and the display device comprises the display substrate. According to the display substrate, the ghosting phenomenon caused by the diffraction effect can be reduced to a certain extent, and the transparent display effect is improved.

Description

technical field [0001] Embodiments of the present disclosure relate to but are not limited to the field of display technology, especially a display substrate and a display device. Background technique [0002] As a new type of light-emitting device, organic light-emitting diode (OLED) has shown great application potential in the fields of display and lighting, and has attracted strong attention from academia and industry. In the field of display, compared with liquid crystal display (LCD), OLED display devices have advantages such as self-luminescence, fast response, wide viewing angle, high brightness, bright colors, light and thin, etc., and are considered to be the next generation display technology. [0003] With the continuous development of display technology, OLED display technology, quantum dot display technology, etc. are more and more used in transparent display. Transparent display is an important personalized display field of display technology. It refers to ima...
